Continental is the most common rubber choice at the Tour. For stage 4, a trend was team leaders and sprinters on 25mm-wide tubualrs, and other riders on 28s

There is no such thing as the one perfect bike for a race day that encompasses tarmac and cobblestones.

As the Tour de France again returned to the pavé this year, riders and mechanics from the 22 teams chose a wide spread of bikes, tubulars and even tubeless setups for stage 4, which many were calling “Paris-Roubaix day” for its resemblance to the spring classic.

Some trends emerged among the teams, with endurance bikes being more common than aero bikes, for instance, and fat 27-30mm tubulars generally carrying the day. But while we did see some of the tall gearing configurations of Paris-Roubaix, such as 54/46-tooth chainrings, there were no triple-wrapped handlebars or knuckles wound in tape to ward off the stones’ harsh vibrations.

Many teams treated stage 4 very much like Paris-Roubaix

On more than a couple of teams, the main sprinter and team leader had 25mm tubulars while their teammates chose 27 or 28mm options.

There was also talk of riders switching bikes mid-stage, as the 13.3km of pavé came almost entirely in the latter half of the race.

Other teams just tinkered with tire pressure, setting it at slightly lower than normal at the start with the reasoning that about half a bar (roughly 7psi) would leak out by the time riders hit the cobbles.

Etixx-Quick Step mechanics were setting one rider’s 26mm tubulars at 5bar, but asked us not to take pictures.

As at Paris-Roubaix, FMB’s handmade tubulars were en vogue. Many were on full display while some were dressed in Specialized treads. Still others were used with the FMB logo and markings blacked out with permanent marker.

No, these aren't FMB Paris-Roubaix tubulars. Why do you ask?

Many sprinters rode their preferred aero bikes. Green jersey holder Andre Greipel set out aboard his green Ridley Noah with 25mm Continental Competition tubulars. Mark Cavendish reverted to his old green Specialized S-Works Venge instead of the brand new Venge ViAS he rode for the first two road stages. He also had narrower casings than his teammates. Katusha’s Alexander Kristoff also held the aero line, piloting the same Canyon Aeroad CF SLX he commanded to wins this spring like the Tour of Flanders, and which he also rode at Paris-Roubaix.

Garmin-Cannondale went the biggest for stage 4, with everyone rolling out on their 30mm FMB Paris-Roubaix tubulars. Team mechanic Alex Banyay said the team used the identical setup from the Hell of the North: Cannondale Synapse bikes with a non-series Shimano front brake installed on the rear for extra clearance. Ryder Hesjedal had a sharply negative mountain bike stem installed to get his desired 17cm of drop on the tall Synapse head tube.

GoPro’s new HERO4 Session showed up on a few rider’s bikes, too.

While the new gopros are smaller than previous iterations, they are still pretty easy to spot: while the new gopros are smaller than previous iterations, they are still pretty easy to spot
